SPALT-DROPPlNG MECHANISM FOR SHlNGLE-SAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 442,171, dated December 9, 1890. Application filed July 21, 1890. $erial No. 359,469. (No model.)

To aZZ whom it may concern.-

Be it known that 1, FRANK CHALLOIIER, of Oshkosh, in the county of Winnebago and State of Yisconsin, have invented certain new and useful Improvements in Spalt-Dropping Mechanism for Shin gle-Sawing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention,

which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of shingle-sawing machines which employ a rotary carriage provided with a number of receptacles or openings for shingle-bolts. Its main 1 object is to discharge the spalts, when dedesignate the same parts in the several figures.

Figure 1 is a plan view of a portion of the carriage in connection with my improved spalt-dropping mechanism. Fig. 2 is a radial vertical section of a portion of the carriage, showing the spalt-droppin g mechanism in elevation. Fig. 3 is a section of the carriage at right angles to that shown in Fig. 2, and shows the spalt-dropping mechanism, lookingtoward the center of the machine; and Fig. 4C is asectional detail on an enlarged scale, showing one of the trip-pins of the carriage and a device for holding it in place.

Z represents a portion of a rotary carriage of a shingle-sawing machine, and c the outer movable dog of one of the shingle-bolt receptacles, all of the usual or any suitable construetion. The outer or movable dogs have central arms on the outside provided with downwardlyprojecting crank-pins upon which are journaled friction-rollers 0. At the proper point for discharging spalts a curved bar a is supported normally just inside of the path of the rollers c by standards I) b, which are fixed at their lower ends to a horizontal rock-shaft (I, held in suitable bearings (not shown) transversely to the diameter of the machine, cutting it through the middle. Upon the shaft (Z is fixed a horizontally-projecting arm I), provided at the end with a friction-roller 11 h is a horizontal shaft placed a little below and transversely to the shaft (Z. It has asuitabledrivingconnection, (ll}Sl10W11,) by which it is continuously driven when the machine is in operation in the direction indicated by the arrow, Fig. 3, and is supported in suitable fixedbearings. (Notshown) Upon the shaft h is loosely mounted a cam g, hearing at its periphery against the friction-roller l) of arm I) and provided with clutch formations or proj ections 15' on its outer face. It is restrained from endwise movement by collars or shoulders on the shaft h. A head (5 is fixed upon the shaft 7L near the outer side of cam g, and is formed with recesses, in which are inserted dogs formed on the inner ends of longitudinally-movable rods t t. These rods 25 t are inserted in longitudinal grooves in shaft h, extend through and are held in place by a box g and are bent outwardly at their outer ends, as shown in Fig. 1, each rod being movable independently of the other into and out of engagement with the projeetionst if on cam g.

c'- is an upright shaft supported in suitable bearings and provided atits upper end with an arm 6, having a horizontal incline at the end, and near the lower end with a similar arm e, having a vertical incline at the end, which is movable by the turning of said shaft 6 inwardly into the path of rotation of the outer ends of the rods t z.

e is an incline attached to the outer end of the box 9 opposite the incline on arm 6 so as to engage with the overhanging ends of rods 15 t and withdraw them from engagement with the projections 15. t on cam g.

Adjacent to each bolt-receptacle the carriage is provided with a vertically-movable pin e, which may be depressed by the operator into range with the incline of arm 0.

19 represents a vertical incline suitably sup- 5 ported in the path of the pins 6 and arranged to return the same to their normal positions after they have been depressed and have acted upon the incline of arm e. The pins 6' are held in place when raised out of range with arm 6 by the device shown in Fig. 4,

which consists of a frictional bearing-piece n,

I inserted and movable longitudinally in a horizontal socket in the carriage Z and held by a spring 0 with an elastic pressure against I the side of the pin 6. The spring 0 bears at the inner end against a head or shoulder on the bearing-piece n and at its outer end against a plug 911, screwed into the said socket.

The arr'ne is held normally out of range With' the enter ends of the rods 15 t by a spring 70, (clearly shown in Fig. 3,) and the dog 0 is forced and held normally in engagement with a shingle-bolt by the usual springs or any suitable device. (Not shown.)

The inecha-nis m herein before described may with slight modification be applied to the in her dogs, and may be otherwise variously modified in its details and arrangem ent without affecting its mode of operation or depart- 3o ing from the spirit of my invention.

- My improved device operates asffollows: Vhen it is desired to discharge a spait from any receptacle in the carriage, the operator depresses the pin e adjacent to the recepta- 3 5 tile. The pin thus depressed engages with the incline of arm 6 and swings it with thearm a inwardly. he latter, engaging with one of the rod'st as it passes, forces it into engagement with a projection t on cam g and 40 "causes the cam to make ahalf-revolu'tion with the "shaft "h, when the outwardly-bent end of the rod 2, riding upon the fixed incline 6 is wi rdrawn fromenga-gement with the projection t, allowing the cam g to come to rest.

While the cam g is thus making a partial revolution the friction-roller b rides over one of the enlarged portions of the cam, and the arm I)" is raised and the standards '1) Z) and curved bar a at their upper ends are swung 5o "outwardly during the interval that the frictionaol'ler =6 is passing outside of said bar. The dog "0' is thereby forced outwardly, so as to release the spalt and allow it to fall out of the carriage. After the pin 6' passes the 5 5 arm e it rides over the fixed incline Q3 and is raised into normal position, in which it is held by the spring-actuated bearing-piece it" until it is again" depressed by the operator.

The "shaft 7L is geared to make one revol=u-- tion while the carriage turns the distance of. one bolt-receptacle, so that, if desired, the
